Abstract While many initiatives, studies and projects are focusing only on modelling wildlife connectivity movement, coordinated efforts should help to deliver adaptative solutions for the on-the-ground needs, while helping the planners and involving communities in landscape protection. Multispecies spatial models and maps allow the generalisation of findings across more significant regions and provide insights to maintain, improve or restore landscape connectivity, while individual species could contribute in establishing regions of focus in conservation efforts. Given the challenge of multispecies connectivity, we chose to build single connectivity models through circuit theory for brown bear, wolf, red deer, wild boar and roe deer. Further, we combined best-supported models in a regional cumulative spatial map, on which we identified areas of high importance for connectivity conservation to investigate and mitigate the impact of linear infrastructure. Results for carnivores and their prey species were similar to those obtained from brown bear landscape genetics modelling. Eastern slope facing was a clear preference of multispecies, and we trust this is due to abundant vegetation, food resources, and lack of fragmentation of forest regions. A vital area called Cold River corridor was validated both functional (brown bear) and structural (for carnivores and prey species) by this study and the results from previous research. However, a highway is planned to bisect the Cold River for the first time, and we advocate that the remaining conservation potential of the area should be maintained whenever possible while planning for evolutionary resilience and prioritizing management actions and effective strategies for all the species. Conservation easements could provide protections against development considered together with coordinated efforts for "smart development", and maintenance of existing forest and wildlife management and land uses preservation.

评估多物种的区域景观连通性,以协调减轻布拉索夫-普拉霍瓦地区线性基础设施影响的实地需求

摘要 虽然许多倡议、研究和项目仅关注对野生动物连通性运动的建模,但协调努力应有助于为实地需求提供适应性解决方案,同时帮助规划者并使社区参与景观保护。多物种空间模型和地图允许对更重要区域的发现进行概括,并为维持、改善或恢复景观连通性提供见解,而单个物种可以有助于建立保护工作的重点区域。鉴于多物种连通性的挑战,我们选择通过电路理论为棕熊、狼、马鹿、野猪和狍建立单一连通性模型。此外,我们在区域累积空间图中结合了最佳支持的模型,我们确定了对连通性保护非常重要的领域,以调查和减轻线性基础设施的影响。食肉动物及其猎物物种的结果与从棕熊景观遗传学建模中获得的结果相似。东坡面是多物种的明显偏好,我们相信这是由于丰富的植被、食物资源和缺乏森林区域的破碎化。本研究和之前的研究结果验证了一个名为冷河走廊的重要区域的功能(棕熊)和结构(对于食肉动物和猎物)。然而,一条高速公路计划首次将冷河一分为二,我们主张应尽可能保持该地区剩余的保护潜力,同时规划进化恢复力并优先考虑所有物种的管理行动和有效策略。保护地役权可以提供保护,防止与“智能开发”的协调努力一起考虑的开发,以及维护现有的森林和野生动物管理和土地利用保护。
